In a major advancement for post‑quantum cybersecurity, American Binary has announced a partnership with Oracle to deliver a radically secure VPN solution designed for both enterprise and defense applications. The joint effort leverages American Binary’s Ambit Client, a VPN built around the rigorous CNSA 2.0 standard, hosted on Oracle Cloud Infrastructure (OCI)(VPN for Defense). This move underscores accelerating demand for quantum‑resistant encryption as organizations prepare for the next generation of cyber‑threats.
What Is the American Binary & Oracle Quantum‑Resistant VPN?
On 3 November 2025, American Binary revealed that it is partnering with Oracle to bring its Ambit Client enterprise VPN to OCI, giving businesses and government agencies access to a quantum-safe communications layer.
Key features of this solution include:
Full CNSA 2.0 Compliance: Ambit Client implements all four cryptographic components required under the U.S. National Security Agency’s CNSA 2.0 standard — digital signatures, key exchange, bulk encryption (AEAD), and hashing. (PR Newswire)
MaxKyber® Protocol: The protocol at the heart of the VPN uses American Binary’s proprietary MaxKyber®, which relies solely on CNSA 2.0-approved post‑quantum algorithms, enabling both interoperability and future-proof security even in bandwidth-limited environments.
Protection Against HNDL Attacks: With this VPN, every data packet is secured against “Harvest‑Now‑Decrypt‑Later” (HNDL) attacks, a class of threats where adversaries collect encrypted data today to decrypt once they possess quantum computing power.
Scalable Deployment on OCI: By hosting Ambit Client on Oracle Cloud Infrastructure, organizations can scale quantum-safe infrastructure rapidly. Deployment is designed to be low friction: accounts and VPN endpoints can be set up in minutes, while on-premise configurations typically take under a day.
Easy to Use: The VPN client is designed for simplicity: once configured, users can initiate a secure connection with a single click, and the system maintains cipher-protected connectivity even amid network disruptions.
Why This Partnership Matters
1. Tackling the Quantum Threat Head-On
Quantum computing poses a real and growing threat to conventional cryptography. As quantum computers mature, they could break many of today’s standard encryption methods. American Binary and Oracle’s VPN solution helps organizations bridge the security gap before quantum computers become powerful enough to break existing systems.
2. Defense & National Security Use‑Case
Because Ambit Client meets NSA CNSA 2.0 standards, it is particularly well-suited for defense, intelligence, and government infrastructure. Wrapping this capability in OCI gives public sector clients a high-assurance, scalable path to quantum-safe communications.
3. Commercial Enterprises Ready for Future‑Proof Infrastructure
Large enterprises that handle highly sensitive data — such as financial services, healthcare, or R&D — can now adopt a VPN solution that safeguards not only against current encryption threats but also against future quantum-enabled attacks.
4. Strategic Synergy
Oracle’s collaboration strengthens its Defense Ecosystem, positioning OCI not just as a high-performance cloud provider but as a platform for cutting-edge, quantum-secure networking. Meanwhile, American Binary gains access to a global, scalable infrastructure for distributing its post-quantum VPN.
Technical Insight: What Makes Ambit Client Unique
CNSA 2.0 Compliance: Many “post-quantum” solutions only implement quantum-safe algorithms for certain parts of the cryptographic stack. Ambit Client is notable because it covers all four CNSA 2.0 components, making it fully compliant.
ML-KEM 1024 Cryptography: The Ambit Client uses a variant of ML-KEM (Key Encapsulation Mechanism) at 1024-bit security, mathematically designed to resist quantum decryption while remaining performant
Optimized Network Performance: Despite the heavy computational requirements of post‑quantum encryption, American Binary says its networking layer is optimized for high throughput and low latency — even when using CNSA 2.0 algorithms across cloud and mobile environments.
Expert Voices & Strategic Commentary
Kevin Kane, CEO of American Binary, puts it clearly: “The quantum threat isn’t a future problem — it’s happening now.”
American Binary’s adoption of the MaxKyber® Protocol — a custom protocol using CNSA 2.0 PQC algorithms — allows the company to deliver both high security and interoperability.
According to the Quantum Computing Report, the VPN is positioned explicitly to counter HNDL attacks, protecting today’s encrypted data from being decrypted in the future by quantum adversaries.
Challenges & Considerations
While the partnership is highly promising, there are some real-world challenges:
Performance Overhead: Post‑quantum cryptography is computationally intensive. Organizations will need to evaluate how Ambit Client’s CNSA 2.0 encryption impacts latency, throughput, and resource usage in their specific environment.
Adoption Cost: Enterprises may be hesitant to migrate to a quantum-safe VPN immediately, particularly if their current infrastructure is deeply invested in traditional cryptographic systems.
Standards Evolution: Although CNSA 2.0 is a rigorous standard, PQC is still a rapidly evolving space. There is a risk that future cryptographic best practices or algorithm standards shift, requiring updates or migrations.
Onboarding & Training: Even with “low-friction deployment,” teams may need training for new workflows, key management strategies, and cloud‑native configurations.

Conclusion
The collaboration between American Binary and Oracle to build a quantum‑resistant VPN via Ambit Client on Oracle Cloud Infrastructure is a bold and forward-looking step in cybersecurity. By fully embracing CNSA 2.0 standards and delivering a practical, scalable deployment path, they’re helping make post‑quantum encryption an operational reality for government and enterprise clients — today, not just for tomorrow.
